9 The Story of ESI Page 1 2 3 4 Next Contacts Corporate Profile
Management Team Product List Backgrounder White Paper The Story of ESI Page Next It all started on a cold night in China in 1978. Ray Hardee was sitting at his desk on the night shift and working with a new TI programmable calculator. He had just finished creating and entering a program for calculating a headloss for a single pipeline, something he did quite often. Once he finished he amazed at how quickly it was able to produce the answers.  He still had to look up an intermediate result in the Mooney diagram in the Crane Technical Paper 410, but it was much faster and accurate. The only problem was when the calculator was turned off the program was erased. He had to manually enter the program each time he wanted to do a pressure drop calculation. He then wondered to himself, “When will they make something that will keep the program?”  Fast forward a few years, its 1981 and Carolyn Popp and Ray were both in Indiana, PA. Carolyn was attending some computer classes at the local university to sharpen her skills prior to re-entering the job market.  “At the time, I was taking some classes on microcomputer programming, the latest thing, and trying to juggle 3 children under the age of 6,” says Carolyn Popp. “This was before IBM started calling them Personal Computers.” She was impressed by the power of those first personal computers and enjoyed the class. Pat Shell an electrical engineer and friend who worked with Ray, had a TRS-80 by RadioShack® and had set up his computer to turn on the electric blanket through an infra-red controller. Both Carolyn and Ray were amazed by what their friend had done. So Ray started looking at getting one of these computers, but at that time they were extremely expensive $5,000 to $6,000 in 1982 dollars. Ray then saw an advertisement for an Osborne OS-1, it was only $1995 and included a Z-80, 8 bit 2 mHz processor with 64Kbytes of memory and two 5.25” floppy drives, a built in monitor, and all the software you would need to start a computer business. Ray and Carolyn started developing PIPE-FLO version 1, taking all the formulas in the Crane Technical Paper 410 and putting them on the computer. The first program had a set of tables for the pipe material, along with the valves and fittings; there was also fluid properties for water, with the ability to add your own fluids. The program was designed so you could create a piping system with 16 pipelines. By the time they really started developing the program Ebasco Services Ray’s employer at the time moved from PA to the Satsop Nuclear unit outside Elma, WA.  Ray went first to check out the area, and Carolyn stayed in Indiana, PA until school was out. She kept the computer, and continued to work on the program. They had the PIPE-FLO design meeting over the phone, and Ray would check out the progress when he got back to Indiana, PA.  Ray submitted an outline for an article to Power Magazine on how micro-computers could be used by engineers to solve real life problems. They accepted the outline, and with a magazine article to his name Ray was a computerized piping expert.  After Carolyn made it to WA and they got settled in and started making real progress on PIPE-FLO. After four months of development they took their program to an engineer that was selling stress analysis software in Seattle.  He had one of his customers look at the program and come back with some suggestions. On the way home from the meeting, Carolyn and Ray were busy on PIPE-FLO version 2.0. With PIPE-FLO version 2.0 we could store up to 100 pipelines into a database. The pipelines could be saved and recalled for later work. They improved _ ©2007 Engineered Software, Inc. Page 1 of 5

Management Team Product List Backgrounder White Paper The Story of ESI Back Next the reports and made it so the customers could create their own pipe size tables.  After another month PIPE-FLO version 2 was finished. They also used a software development tool that let them easily configure the program for the wide range of computer terminals that were available.  “We were in business with a program, but we didn’t have any customers,” says Ray. “See we first had to sell the prospect on the idea of buying a micro computer and then to buy our software.”  About this time, IBM® released the Personal Computer and the TV was full of IBM PC ads with Charlie Chaplin showing us all why we needed a PC. Now that they didn’t have to convince prospective customers they needed a computer, they could concentrate on developing the software and selling it. Ray and Carolyn finally took out a business license for Engineered Software in About the same time a 20 year old Bill Gates was starting up his company, they had about 30 employees, Engineered Software, Inc. (officially named) had two employees.  Rather than learn how to sell software, Ray and Carolyn decided to create a new program. ORI-FLO was developed to size flow meters and orifices. Much of the information about the pipe and fluid needed by ORI-FLO could come from the “Pipeline Database” created by PIPE-FLO. ORI-FLO 2.0 (there never was an ORI-FLO 1.0) was finished in about one month and they had another product. Once again rather than learn how to sell software, they developed another program called SYS-FLO. Using this program you could take the pipelines designed by PIPE-FLO , insert them into the Pipeline Database and connect them together into a series segments and parallel segments. You could also put in a pump and say how much flow rate you wanted, the program would calculate the pressures along the way and the flow rates in the parallel segments for you. Carolyn had to create screen in which you could choose a series or parallel segment and then enter the pipe lines for the pipeline database.  This was a really cool program and after a couple of months they had their third program. Since Engineered Software had three programs that worked together on fluid piping systems they called the programs together, the “FLO-SERIES.” Now they figured they needed to sell some programs because after all, to call themselves a business they needed some paying customers.  In 1984 the PC was the talk of the town and KIRO (the local Seattle TV and Radio station) decided to have a computer show at the Seattle Center. Ray figured that since their customers needed to have a computer, why not go to a trade show attended by people who were interested in computers.  “We got a sign painted and it looked great we put it on ¾ inch marine plywood so it would last, I believe it cost us $50,” says Ray.  They took their computers (now they had two) to Seattle and exhibited in the trade show. It lasted from Thursday to Sunday and was open from 10:30 am to 7:30 pm. Carolyn and Ray both spent the whole time in the booth. After four days showing the software to fellow computer geeks, mothers who wanted to make sure they purchased the right computers for their kids, and an occasional engineer who found our booth, they got a handful of leads and felt tired but were pleased. During that show they made an appointment to demonstrate the program to the Puget Sound Naval Shipyard and that’s where they made their first big sale.  ©2007 Engineered Software, Inc.

11 The Story of ESI Back 1 2 3 4 Next Contacts Corporate Profile
Management Team Product List Backgrounder White Paper The Story of ESI Back Next After that first show, they decided to start advertising in the Osborne User Group magazine, and once again were advertising to engineers that already had computers. That gained a couple of sales to Bechtel, their second customers. The next trade show they went to was hosted by the American Society of Mechanical Engineers, and had to do with piping systems. Really pipe stress, but at least it was visited by engineers involved with piping systems. They didn’t have any booths, but they did have a poster session so they put their trusty Engineered Software sign of ¾ inch plywood, in the poster session and directed attendees to their suite. It was really a room in the conference hotel and they had a large number of prospective customers stopping by. They liked what they saw but they wanted a more flexible program one that would do network of pipelines. Engineered Software started working on NET-FLO, their fourth program. It would allow you to build a network of pipelines, pumps, and components and calculate the balanced pressures and flow rates for each pipeline in the system. They got a copy of the source code of the University of Kentucky KY PIPE program. Carolyn spent about two months understanding how the loop tracing and calculation algorithms worked. For the next three months she worked on the program during the day, and Ray checked the results for her at night. Carolyn would fix the bugs as Ray found them. Both were working on nights and weekends so, after four months, NET-FLO was complete and they had developed an easy to use network analysis program that was fast and provided accurate results.  “We really felt we had a winner that the market would like,” Ray says. NET-FLO got the pipe information from the Pipeline Database created by the PIPE-FLO program. Now there was four programs in the FLO-SERIES so they started focusing on selling some software. Employing a few high school students to put in pump curves with Ray while Carolyn continued to develop and add more functionality to the programs. During that time, the FLO-SERIES version 3 (comprised of PIPE-FLO, NET-FLO, PUMP-FLO, CON-FLO, and ORI-FLO) became a set of DOS programs which together included the basics of what we now call PIPE-FLO. Ray did all of the sales & marketing, and Engineered Software started to become known among engineering firms. After working at the Satsop plant in Elma for two years, Ray finally got the word that WPPSS ran out of money and they were going to be closing the plant.  “I had a choice of staying with Ebasco and moving, or quitting the day job,” says Ray. “I chose to quit the day job and I started working for Engineered Software full time with Carolyn.”  Around 1988, Engineered Software landed a contract with Aurora Pump to do a custom pump selection program under Windows (version 1 just released), which involved completely rewriting PUMP-FLO in a new language and OS. This was a big turning point in development and increased their good exposure. ©2007 Engineered Software, Inc.

Management Team Product List Backgrounder White Paper The Story of ESI Back In 1989, Ray and Carolyn moved their business to a slightly larger office in downtown Olympia, Washington.  Over a period of six years, Engineered Software grew to a company with seven employees operating in 900 sq. ft. Working with two interns, they converted the remaining FLO-SERIES programs to the Windows interface, which included the first FLO-Sheet interface for PIPE-FLO  and it was named FLO-SERIES version 5. Sales started moving along, but they were still figuring out how to make Engineered Software, a successful company. In 1996 Engineered Software had built and moved into a small office in Tumwater, Washington. First occupying only half of the building, then slowly over 10 years growing into a company with over 22 people. They established a software development group and a sales force, and every year showed steady growth. This starts the second chapter of Engineered Software. ©2007 Engineered Software, Inc. Page 4 of 5

13 Using Fluid Flow Software in Plant Operations
Contacts Corporate Profile Management Team Product List Backgrounder White Paper Page Next Using Fluid Flow Software in Plant Operations By Ray Hardee P.E. Introduction Fluid flow software provides a clear picture of how a piping system operates by calculating the flow rates and pressures in the system. Initially this software was mainly used to design the piping system, but recently more plant personnel are using this type of software to simulate the operation of existing fluid piping systems. To become more useful for plant personnel, the software has to be easy to use while showing the interaction of the pipelines, pumps, components, and control valves in the system. In addition, the information has to be easy to share with others and provide access to information needed to operate and maintain the fluid piping system. This white paper describes how PIPE-FLO, a fluid flow computer program developed by Engineered Software, provides owners and operators of piping systems with the tools they need to gain a clear picture of their system operation. Examples are presented that show how this software is currently meeting the needs of the plant operating market. Total Picture To be effective in the plant operating market, the piping software must provide the user with sufficient information to design, build, operate, and maintain the system through the plant life. The total picture provides the user with information he or she needs to fully understand the operation of the system. To provide this total picture, PIPE-FLO includes the following features: A piping schematic showing how the items in the system are connected A calculation engine capable of showing the flow rates and pressures within the piping system and highlighting problem areas The ability to easily communicate with others as to how the system operates Access to information needed to design, build, operate, and maintain the piping system Other programs can provide the user with one or more of the necessary features, but the value of PIPE-FLO is the integration of these tasks into a single application. Visualization The first step is providing the user with a clear picture of how the items in a piping system are connected. Piping schematics show the location of tanks, pumps, components, control valves, and pipelines and how they are connected. A piping schematic identifies each item in the system using the project’s equipment naming convention. Piping schematic drawings can be created using CAD software, providing the user with the ability to easily maintain these design documents. General purpose CAD software has a long list of features making it useful for other types of drawings as well. But the large feature set of CAD software results in a steep learning curve one must overcome to effectively utilize the software.  Page 1 of 5 ©2006 Engineered Software, Inc.

14 Using Fluid Flow Software in Plant Operations By Ray Hardee, P.E.
Contacts Corporate Profile Management Team Product List Backgrounder White Paper Back Next Using Fluid Flow Software in Plant Operations By Ray Hardee, P.E. During PIPE-FLO’s development, the drawing features were limited to those needed to develop a 2-D piping schematic. This approach makes it much easier to learn how to use the software. PIPE-FLO’s drawing feature set includes the ability to: Place pre-defined piping system objects (tanks, pumps, components, control valves, and pipelines) on the schematic drawing Name items on the schematic drawing using the plant customer’s naming convention Insert text and call out boxes on the piping schematic providing greater presentation value to the schematic drawing Incorporate typical CAD features such as zoom, pan, snap, edit, object copy, and group copy to make it easier to create and update the schematic. PIPE-FLO uses the piping schematic in each stage of the process such as selecting the object to enter or edit data, viewing piping system information and displaying calculated results. Calculation PIPE-FLO calculates the balanced flow rates and pressures in piping systems. It can handle open or closed loop systems, as well as series, branching, and parallel flow paths. The following features are included in PIPE-FLO’s calculation engine: The piping schematic drawing is used to automatically set up the equations necessary to calculate the balanced flow rates and pressures Engineering data tables store pipe, valve, and fluid properties needed to calculate the balanced flow rates and pressures Sizing rules and design limits assist the user in optimizing individual pipelines during the design process The software uses the calculated results to assist in selecting and inserting pump and control valves from manufacturer supplied Electronic Catalogs The ability to set up and save various operating scenarios or lineups so the user can see how the system operates under a variety of expected operating conditions This approach also allows the user to optimize the piping system as it is being built, providing a better final design. Using these calculation techniques, the user is able to quickly build the piping system model without having to get involved with the program’s inner workings. Communications Communication is necessary to insure the various groups involved in the project have a clear understanding of how the piping system is to be built and operated. To insure a system is built to meet the requirements of the end user, specification documents are developed outlining the methods for each item’s design, construction, and testing. During the design process the information must be checked and reviewed by other members of the design team. After the system design is completed, the owner of the piping system must review the information. Page 2 of 5 ©2006 Engineered Software, Inc.

15 Using Fluid Flow Software in Plant Operations By Ray Hardee, P.E.
Contacts Corporate Profile Management Team Product List Backgrounder White Paper Back Next Using Fluid Flow Software in Plant Operations By Ray Hardee, P.E. To accomplish these various communication tasks, PIPE-FLO: Uses pipe specifications to outline the pipe material and valve tables for various piping applications Saves pipe specifications in design files which can be used as templates when creating a new system Engineering data tables can be modified to provide further design control All program reports can be printed to Portable Document Format (PDF) files and ed directly from PIPE-FLO Projects can be shared with others in a Piping System View (PSV) file format; using the free PIPE-FLO Viewer program, the PSV file can be opened and the recipient can see how the system operates The ability to communicate with others insures everyone involved with the project has access to all the information needed to design, build, operate, and maintain a fluid piping system. Access Many of the documents required to design, build, operate and maintain a fluid piping systems are available in electronic format. Using the programs FLO-Link feature, hypertext links can be created within the FLO-Sheet to design documents located on the Internet or on a network. For example, a pipeline on the FLO-Sheet can have a FLO-Link to the piping isometric drawing done under a CAD program. Links can be created to maintenance manuals, spare parts lists, and dimensional drawings. FLO-Links can also be used to start other programs. For example, a FLO-Link associated with a pump on the FLO-Sheet can start up the plant’s maintenance management software and display the maintenance history for the selected pump. Building the System Model Building the system model involves entering the details about each item in the piping system. Much of the information needed to build the model is obtained during the design process. It is always best to create the model during the design process and keep the model current through construction and startup. This allows you to turn over a completed piping system model to the client as part of the required design package. Design document The PIPE-FLO project file provides the user with the ability to store and update piping system design details as they become available. For example, when doing a preliminary design the pipe diameter and number of isolation and check valves is determined. The length of pipe and number of elbows is approximated. Once the pipe routing is completed, the exact length of pipe and number of elbows is known, and the piping system model can be updated. As the various design and equipment document packages become available, FLO-Links can be added to the PIPE-FLO model. By creating the FLO-Links when the information becomes available, the piping system model is always current and can be used to quickly access information about each item in the piping system. At the end of the design phase, the engineering documents can be turned over to construction for use in building the system.  Page 3 of 5 ©2006 Engineered Software, Inc.

Contacts Corporate Profile Management Team Product List Backgrounder White Paper Back Next Using Fluid Flow Software in Plant Operations By Ray Hardee, P.E. Construction document During the construction process, the design documents are used to build and test the system. In this phase of the project, field changes are often necessary to accommodate changes in pipe routing or changes in the system design. If the modifications involve adding pipe length, elbows, or changes to the pipe sizes, the piping system model can be quickly updated and calculations performed to show the effect these changes have on the piping system operation. During plant startup and testing, the PIPE-FLO model provides the plant startup engineers with a model that shows how the system will operate. This information is very useful during startup because much of the equipment testing is done with the equipment running in abnormal operating conditions. Using PIPE-FLO, a copy of the design model can be created and the operating conditions can be adjusted to reflect how the test will be run. PIPE-FLO can also be used while flushing the piping system to remove construction debris. A copy of the piping system model can be created and the startup engineer can insert the strainers, filters and piping jumpers needed to flush the system. PIPE-FLO can then calculate the flush velocities for each flush path. In addition, PIPE-FLO can calculate if a pump is operating off of its pump curve due to abnormal operating conditions encountered during the flushing operations. The PIPE-FLO model also shows how the system should operate under various pre-operational test conditions. Many of these tests are performed at off-normal operating conditions and a piping system model provides indication of how the system will operate during these tests. Finally, the program can calculate the valve positions needed to balance the flow rates in the piping system. Validating the model After the system is built and while it is put into operation, the piping model should be validated. The PIPE-FLO model shows how the system is designed to operate. The plant instrumentation shows how the plant is actually operating. If the PIPE-FLO model matches the observed plant operating conditions, the model accurately reflects the actual system operation and it is a valid model. Once the validation is performed for a variety of operating conditions, the model can be used to predict system operation under any possible set of operating conditions. Troubleshooting System Operations After the system has been turned over to the operating plant, the PIPE-FLO model can be used to troubleshoot system operation. If the predicted results of the piping system model do not agree with the observed plant operating data, then either the model is incorrect, or something in the piping system is not operating as designed. This information can be valuable in troubleshooting piping systems. For example if the flow rate through a system is low, the problem could be caused by a: Valve out of position System blockage Pump problem Control valve problem Page 4 of 5 ©2006 Engineered Software, Inc.

A piping system lineup can be created so the model is set up exactly like the real system is operating. By comparing the observed values of the operating system with the piping system model, one can quickly isolate the problem and, more importantly, determine what can be done to return the system to normal operation. Plant Improvements & Modifications During the life of the plant, changes will be made to system because of process changes, the addition of new loads, or the need to increase capacity. Using the existing piping system model, the project engineer can see how the required changes will affect the operation of the system. For example, an engineer in a chemical plant in Deer Park Texas was faced with the need to increase the capacity of a service water system. It was determined that an additional pump in parallel should be added to increase the system capacity. After the plant engineer evaluated the piping system with PIPE-FLO, he noticed that over 1/3 of the system losses occurred in a 90 ft section of the 36-inch pump discharge header. Using the PIPE-FLO, model he determined that if the 36-inch discharge header was replaced with a 48-inch header, the existing pump could handle the additional system load. The resulting reduction in pipeline loss in the discharge header eliminated the need to add a third pump, resulting in a savings in capital cost of over $100,000. This modification also reduced the system head loss, resulting in lower pumping costs. Training & Operations Plant operating personnel need to know how the plant will operate during a variety of conditions. They can either gain that experiencing by actually putting the plant into that condition, or they can simulate the operation using piping analysis software. In many cases, the piping system is infrequently operated at given conditions, such as startup or shutdown, making it difficult for operating personnel to obtain necessary experience. In other cases the system cannot be operated in that condition due to operational requirements. Using PIPE-FLO, an operator can safely simulate the operation of the piping system in these infrequent or potentially dangerous system operating conditions, allowing a plant operator to gain experience in system operation without affecting the operation of the physical plant. Conclusion PIPE-FLO provides a clear picture of the operation of a fluid piping system; as a result, the model is a valuable design document for anyone involved with the system. If the model is started during the design phase, updated during construction, and maintained for the life of the plant, a clear picture of the piping system operation is always available.  Page 5 of 5 ©2006 Engineered Software, Inc.
